There already are W3C "recommendations" for embedding XML in HTML without
having character data be displayed. See http://www.w3.org/TR/NOTE-xh.html.
The best 3 are:
<SCRIPT LANGUAGE="XML">
<!-- XML goes here -->
</SCRIPT>
<SCRIPT TYPE="text/xml">
<!-- XML goes here -->
</SCRIPT>
<XML>
<!-- XML goes here -->
</XML>
